I think that you are off to a good start here. I'm loving the ambiguity of the opening scenes as well as the descriptive area that you have about Kaya. I'm assuming that you'll elaborate more on her character as the story progresses.

As for characterization, I'm liking your original character already. She seems to have quite an edge to her. I'll have to talk more about her in the later chapter as this is just the beginning. Good job so far!

Although I did see a few grammatical errors, as well as some comma usage/ position issues. Don't worry those can easily be fixed ^_^ This chapter also felt a little to abrupt due to its length. However, you did give us (the readers) a fair warning that this was the introductory chapter, I can let this slide ;)

As I had mentioned earlier, I like how your introduction really opened up a lot of opportunities for you story! It really places your readers at a position that keeps their curiosity rolling. Good job!
